Do I Need to Get a Vitamin B12 Deficiency Diagnosis Before Taking Vitamin B12

by Cathy

Do I need a Urinary Methyl Malonic Acid test & blood serum homocysteine tests for accurate diagnosis or are my symptoms enough to determine if I have a low B12? My Blood Serum B12 reads 609ng/L and I am told the norm is between 175 - 900 but I feel quite unwell and have all the symptoms of B12 deficiency.

I can't tell you that

Hi Cathy,

Unfortunately, I can't tell you whether you 'should' or 'should not' get a diagnosis or take any tests before you start taking Vitamin B12 if you have many of the symptoms of deficiency.

I can point you to my page on Vitamin B12 Deficiency Treatment and you can see what has been the experiences of other women with fatigue who had normal vitamin B12 levels and who took Vitamin B12.

but I can only provide information, I cannot tell you whether you 'should' get a diagnosis or not first. But one question that you might want to ask yourself is: What would happen if I did take vitamin b12 without a diagnosis of deficiency and I didn't have a deficiency. What happened to the women in the study on the Vitamin B12 Deficiency Treatment page when THEY took Vitamin B12 and they didn't wait to get a Methylmalonic Acid Test?
